Abstract
The utility model provides a low-voltage reactive-power compensation cabinet, wherein due to the adoption of the switching mode of a plurality of groups of capacitors connected in parallel with each other, the power factor of the electrical network is automatically improved, while the loss of both an entire system and a transformer are lowered. Therefore, the quality of the electric energy provided by the electrical network is improved and the energy-saving purpose is realized. According to the technical scheme of the utility model, the low-voltage reactive-power compensation cabinet comprises a cabinet body. A transformer is arranged in the cabinet body. The transformer in the cabinet body is connected with at least two capacitors connected in parallel with each other. All the capacitors are connected in series with an anti-harmonic reactor. The panel of the cabinet body is provided with an ammeter, a power factor meter and a change-over switch. Furthermore, the top of the interior of the cabinet body is provided with a cooling fan.
Description
Technical field
The utility model relates to the controller switching equipment field, is specifically related to a kind of low voltage reactive compensation cabinet.
Background technology
In low voltage reactive compensation cabinet, in cabinet, the own loss of transformer and entire system is very large, and it has caused energy waste; The higher occasion at harmonic wave, if compensating cabinet self does not suppress the parts of harmonic wave, more inner components and parts are very easy to be interfered.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, a kind of low voltage reactive compensation cabinet is provided, it is by the mode of many group shunt capacitor switchings, automatically improve power factor of electric network, reduction system and transformer loss, thereby improve the electrical network quality of power supply, reach energy-conservation purpose.
The utility model solves the technical scheme that its technical problem adopts: a kind of low voltage reactive compensation cabinet, comprise cabinet, transformer is installed in cabinet, and the transformer in cabinet is connected with at least two capacitors parallel with one another, and all capacitors are all connected one and resisted humorous wave reactor;
On the cabinet panel of above-mentioned cabinet, ammeter is installed, power factor meter and change over switch.
Further: the top of above-mentioned cabinet inside also is equipped with refrigerating fan.
The utility model compared with prior art has the following advantages:
A kind of low voltage reactive compensation cabinet of the utility model, connect multiple unit capacitor parallel with one another by the transformer in cabinet, mode by many groups shunt capacitor switching, automatically improve power factor of electric network, reduction system and transformer loss, thereby improve the electrical network quality of power supply, reach energy-conservation purpose; In order to guarantee the stability of capacitor, also be in series with anti-humorous wave reactor on capacitor of the present utility model, it guarantees the operation of capacitor stability and safety.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
The 1-cabinet, the 2-ammeter, the 3-power factor meter, the 4-refrigerating fan, the 5-change over switch, the 6-transformer, the 7-capacitor, 8-resists humorous wave reactor.
Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
As shown in Figure 1, it shows embodiment of the present utility model, a kind of low voltage reactive compensation cabinet of the utility model, comprise cabinet 1, transformer 6 is installed in cabinet 1, transformer in cabinet 1 is connected with at least two capacitors parallel with one another 7, and all capacitors 7 are all connected one and resisted humorous wave reactor 8;
On the cabinet panel of above-mentioned cabinet 1, ammeter 2 is installed, power factor meter 3 and change over switch 5.
Further, the top of above-mentioned cabinet 1 inside also is equipped with refrigerating fan 4.
The utility model, by the mode of many group shunt capacitor switchings, improves power factor of electric network automatically, reduction system and transformer loss, thus improve the electrical network quality of power supply, reach energy-conservation purpose;
The low voltage reactive compensation cabinet main components is comprised of knife switch or switch with knifeshaped fuse, current transformer, lightning arrester, fuse, electric mechanical switch (contactor), thermal relay, self-healing low-voltage capacitor and Intelligent Reactive Compensating Controller;
On cabinet panel of the present utility model, ammeter, power factor meter, change over switch etc. are arranged, facilitate the user to carry out real-time monitored and the conversion of manual/auto switching; The fan of heat transmission can be installed according to user's request in the cabinet upper back, to carrying out air blast cooling in cabinet;
The higher occasion at harmonic wave, the utility model reactive compensation cabinet, by the anti-humorous wave reactor with capacitor's series, suppresses harmonic wave, the capacitor for voltage protection safe operation.
The above is explained in detail the utility model preferred implementation by reference to the accompanying drawings, but the utility model is not limited to above-mentioned execution mode, in the ken possessed those of ordinary skills, can also under the prerequisite that does not break away from the utility model aim, make a variety of changes.
